Figure 1. Differentially expressed immune-related genes and transcription factors (TFs). Heatmap (A) and volcano plot (C) demonstrating differentially expressed genes between hepatocellular carcinoma (LIHC) and non-tumor tissues. Differentially expressed immune-related genes (IRGs) are shown in heatmap (B) and volcano plot (D), red and green dots represent differentially expressed genes. Heatmap (E) and volcano plot (F) illustrating differentially TFs between LIHC and non-tumor tissues, red dots represent differentially up-regulated TFs. Red dots represent differentially up-regulated expressed genes, green dots represent differentially down-regulated expressed genes and black dots represent no differentially expressed genes. N, normal tissue. T, tumor.
